Synthesis of CoCrFeNiMnW0.25 High-Entropy Alloy Powders by Mechanical Alloying and Plasma Spheroidization Processes for Additive Manufacturing

다국어 초록 (Multilingual Abstract)

Spherical powders of CoCrFeNiMnW0.25high-entropy alloy were obtained from elemental powders by mechanical alloying(MA) at various energy modes followed by plasma spheroidization. Samples obtained from low-energy MA-powdershave an inhomogeneous microstructure and phase composition. Samples obtained from MA-powders with homogeneousstructures have a high degree of sphericity and chemical homogeneity; the face-centered cubic solid solution represents thephase composition of the powders. The resulting powders can be used in powder-based additive manufacturing technologies.
